The ESP32S is a Wi-Fi Development Board with in-built Bluetooth Low Energy (BLE) that is commonly used in IoT applications. The Board is based on the ESP WROOM32 Module from Espressif Systems. The compact Module can work on 3.3V and consumes low power making it suitable for portable battery powered applications.

It has a dual mode 2.4 GHz Wi-Fi with 40nm low power TSMC technology making it safe reliable and scalable.  The board also has a CP2102 USB-UART bridge making it easier to use serial communication for debugging. The Board can be used with Arduino IDE and also with Lua Programming Environment.

Product Description of ESP32S Development Board

The ESP32 is a successor of the ESP 8266 board. It is has a dual core processor and it combines both Wi-Fi and Bluetooth capabilities. The board has a USB-to UART interface so that it can be easily programmed with popular Development environments like Arduino IDE. It can be powered through the Micro USB port, the 3.3V pin or the Vin pin.
